↑Barnes, Constantine and Eusebius, 6–7; Potter, 282; Southern, 141–42. The chronology of Maximian's appointment to Augustus is somewhat uncertain (Corcoran, "Before Constantine", 40; Southern, 142). It is sometimes suggested that Maximian was appointed Augustus from Hulyo 285, and never appointed Caesar. This suggestion has not received much support (Potter, 281; Southern, 142; following De Casearibus 39.17).
